Abstract

SE PROPONE UN METODO Y UN DISPOSITIVO PARA LA FABRICACION DE SENSORESPREVISTOS EN PARTICULAR PARA LA DETERMINACION DE FUERZAS DE PRESION. EN LA TECNICA DE CAPA GRUESA SE APLICA PRIMERAMENTE POR LO MENOS SOBRE UNA PLACA SOPORTE (10) UNA CAPA AISLANTE (14), SOBRE ELLA UNA CAPA RESISTIVA SENSIBLE A LA PRESION (12) Y FINALMENTE PISTAS CONDUCTORAS (13). EL CONJUNTO DE LA CAPA (1114) SE COMPRIME A CONTINUACION JUNTO CON UNA MASA DE MOLDEO DE PLASTICO (15) EN UNA ESTAMPA DE COMPRESION (20-22). A CONTINUACION SE RETIRA LA PLACA SOPORTE (10) DE LA PIEZA PRENSADA.A METHOD AND A DEVICE FOR THE MANUFACTURE OF SPECIFIC SENSORS IS PROPOSED IN PARTICULAR FOR THE DETERMINATION OF PRESSURE FORCES. IN THE THICK LAYER TECHNIQUE AT LEAST APPLIES AT LEAST ON A SUPPORT PLATE (10) AN INSULATING LAYER (14), ON IT A PRESSURE SENSITIVE RESISTIVE LAYER (12) AND FINALLY CONDUCTIVE TRACKS (13). THE LAYER ASSEMBLY (1114) IS COMPRESSED BELOW TOGETHER WITH A PLASTIC MOLDING MASS (15) IN A COMPRESSION STAMP (20-22). THEN THE SUPPORT PLATE (10) IS REMOVED FROM THE PRESSED PART.
